Bowenite and Lazurite Chemical Formula
While comparing Bowenite and Lazurite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Bowenite and Lazurite chemical formula.

Bowenite and Lazurite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Bowenite and Lazurite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Bowenite and Lazurite Optical Properties during the identification of gemstone. Specific gravity of Bowenite is 2.75 whereas that of Lazurite is 2.75.
